So, if we use Eberron as a theoretical model:Interestingly enough there are only 134 pages in the 320 page book devoted in geography (regions) including Realms and a single page on other continents, 44 pages for Character options, not including spells, 27 pages on deities and the cosmology, 6 pages on History, 7 pages on running the realms, magic got 12 pages. Within the geography section the Dalelands got a staggering chunk of space compared to everything else.
There is there is alot of room to shift space around within the 320 pages. Character Options don't take up nearly as much space, compare the space Prestige Classes take up, each of which is a quarter to half a regular class in size, to the small space subclasses take up. Lineages don't take up much space either, even if their is alot of them, although a deeper dive into cultural lore will. I think even at 320 pages they could make the Geographic (regions) section much bigger thanks to space saved in other sections and partly by the simple fact that books like the adventures already released, the SCAG, etc..., already have done alot of the work.
If they go with MM size instead they can go even deeper on regions or add more stuff.
- Chapter 1: character options. Update traditional Races yo Tasha Lineages, New Subclasses, maybe Tealms specific Group Patrons.
- Chapter 2: Faerûn Gazateer, focused on areas outside the Sword Coast, similar to Rising from the Last Wars Chapter 2.
- Chapter 3: Dalelands deep dive Gazateer, similar to the Sharn Chapter, considering the amount of material generated for the Dalelands by Greenwood, and the area being well suited to D&D High Fantasy mercenary adventuring parties.
- Chapter 4: Adventure generation material: tables, maps, seeds, the whole nine yards. Includes a starting adventure module set in the Dalelands.
- Chapter 5: Magic items & treasure.
- Chapter 6: Bestiary
